Kyosho Inferno GT2 VE - Big-Block Edition

[Dr_T]

Did some simple no-load testing of the TP5660; used the XL2's datalogging only, which appears to have a bit too low of a Current resolution for accurate figures, but I was too lazy to solder TRX-to-XT150 adapters for my Power meter and you probably get the picture.

Seems those D-winds are pretty power-hungry compared to Y-winds indeed, with quite high no-load Currents. Compared to my TP4070 with identical kv, but Y-wind, I measured this TP5660 D-wind to have about 2.5 times higher no-load Current. Measurements seem to correlate more-or-less with the new TP5660 specs though (although I'm not sure what the reference Voltage is in those specs).

First plot shows max throttle response @ 14.1 V, for 0, 2, 4, 6, 8, 10, 12, and 14 deg timing. Second plot shows some DIY step response with a 6S pack at storage Voltage, for 0 (left) and 5 deg (right) timing. Last pic shows numeric summary of the datalog plots, plus a rough plot of the relationship between the no-load Power and RPM. Interestingly, it seems to take more Power (I*V) to spin the motor with a certain RPM at 14.1 V than at 22.2 V. As I translated the differences in Io already to Power, they should be fully comparable, so can't make any sense of that yet... maybe the ESC is involved in these differences too?
